Question

Which word group is a complex sentence?
a. a plane roared overhead, and walt covered his ears.
b. our town is clean and safe.
c. tommy came when eve called him.
d. the waiter smiled and took my order?

Answer 1

The answer is C. Tommy came when Eve called him. This is a complex sentence because "Tommy came" can stand on its own, its the independent clause. "when eve called him" cannot be its own sentence, its linked with "Tommy came" and is a dependent clause. Put these two together with the use of a conjunction "when" and a complex sentence is formed.
